Each individual is composed of one or more minimal living units, called cells, and is capable of transformation of carbon -based and other compounds (metabolism), growth, and participation in reproductive acts.

Life is a characteristic of a living organism that distinguishes the latter from a dead organism or a non-living thing, as specifically distinguished by the capacity to grow, metabolize, respond (to stimuli), adapt, and reproduce.
